Drinking water(cold)

The problemsCorrosion

● The concentration of ions is increasing.The following ions are a particular riskfor metal materials:Chlorides: stainless steelSulphates: galvanised steelNitrates: copper

● Even more problematic sources of water are being used for drinking water supplies

● Acid rain lowers the pH value of surfacewater and spring water to below 7 (=neutral). External corrosive attacksfrom new building materials, insulatingmaterials and installation techniques

● Disinfectants (chlorine, ozone) are particularly aggressive on copper, releasing poisonous copper ions intothe water supply.

Deposits

● Hard water leads to the formation ofdeposits on the inside walls of metalmaterials .

This results in:

● Higher friction losses● Reduced flow rate● Blockages● Expensive repairs● Time-consuming renovation● Acute supply problems

A secure supply ofdrinking water is anessential factor fora high quality of life

Advantages● Range: d20 – d125

All the necessary fittings and adaptors

● High chemical resistance tocompressor oils

● No corrosion. This ensures thatthe quality of the compressedair is maintained

● No energy loss caused byleakage through dried seals

● The smooth surface means thereare low friction losses and no narrowing of the cross-sectionin the fitting.As a result of the this and the elasticity of the material thereis a low noise transmission

Applications● Driving medium for tools such as

drilling machines, hammer-drive screws, grinding machines,pressure cylinders …

● Pneumatic control systemsfor machines

● Driving force for regulating fittings,solenoid valves, shut-off devices,valves …

● Purification air at the workplace

Compressed airtechnology PN16Compressed air is now an integralpart of the manufacturing andprocessing industries.

There are numerous tasks and thesolution is often simple. However,the quality of the piping and itslong term properties play a decisiverole in the safety and the costs.

Chilled waterPipe systems for chilled water coolingsystems (from fan coil systems to ceilingcooling systems) must be safe to use,flexible in design and quick to install.

KEtrix® meets all theserequirements:

● The highly secure welding jointtechnology with a safety factor >3

● NONOX® process ensures no oxygen diffusion

● Resistant to chemicals, aqueous solutions and water hammer,even at cold temperatures.

● Resistant to corrosion, even at points where there is unwanted condensation

● Complete fitting programme which has been adapted for each application

● The low weight and easy handling means that many joints can be pre-manufactured in the workshop.This saves time and costs

● KE KELIT pre-manufactures fitting components which are required in large numbers

Cooling systemsThere are only a few types of plastic whichare resistant to impact at lowtemperatures, resistant to corrosion andhave a reasonable relationship of priceto performance.

CRYOLEN®, a polypropylene alloy(POB = Polyolefine blend) meets theserequirements:

● High impact resistance at temperaturesdown to –30°C

● Resistant to glycol brines whatever the concentration

● NONOX® process ensures no oxygen diffusion

● Resistant to corrosion, even at pointswhere there is unwanted condensationand at temperatures around 0°C.

● No pre-treatment (painting) ofthe pipes required

● Safe. In comparison to steel/copper/stainless steel a very quick welded joint

Cooling technology

Insulation● In most cases with cooling systems

a specialist insulating contractor will install the insulation with a suitable and approved elastomer foam and will ensure that it is sealed to stop diffusion

● Straight lengths of pipes are also available with polyurethane insulation(see pages 12 and 13)

The polyfusion weldingtechnology assures clean,leak-free, secure andhomogeneous joints.Pressure rating: PN16

Impermeabilityto oxygenThe molecular structure of the polymersmeans that small amounts gases diffusethrough the material at different rates.

The problem is well-known:● Carbonated drinks should not lose

any CO2

● Many foods need to be protectedfrom the effects of O2(fats, oils, milk cheese, meat…)

● On the other hand aromas shouldnot escape(coffee, jam, vegetables….)

● Sheets act as water vapour barriersin buildings Pipes in water circulationsystems must not allow oxygen to diffuse through the pipe as this will attack the metal components and cause the following problems:– Corrosion (Iron, steel)– Incrustation– Blockages– Malfunctioning– Expensive repairs

In general these problems are solvedby using composite materials:

A combination of plastic material withother materials which provide strength ora barrier to oxygen diffusion E.g.– EVOH to prevent O2 diffusion– Fluorine polymers to prevent

H2O vapour– PA to prevent diffusion of oils

and fuels– Metal to prevent the loss of aroma

The NONOX® processKE KELIT has developed a newpatented process:

The structure of the polymer alloy makesit possible to close the ”molecular pores”by means of a ”redox” treatment.O2 molecules can no longer diffusethrough the material.

The resultKEtrix® pipes, which are madecompletely of plastic areimpermeable to oxygen when thewall thickness is a minimumof 3,7 mm.

The material was tested to ÖNORM B5157according to the zinc absorption method.

Test reports by the TGM institute in Viennashowed the following results:

Max. diffusiondefined by standard: 0.1 mg O2/d .m3

Result for Ketrix: < 0.005 mg O2/d .m3

KEtrix® is made of CRYOLEN®Polyolefine blend (POB).A polypropylene alloy with excellentproperties.

CRYOLEN® is a heterogeneous materialbut for the purpose of testing is classifiedas a type of PP-B in accordance withÖNORM B5174

Metal thread fittings

Special attention has been paid to thechoice and quality control of the metalthreads.

Special quality properties:● Dezincification resistant brass

(MS 63, CZ 132) for all parts which transport water ensures a high resistance to aggressive water.

● A pore-free, chemically applied,nickel plating prevents stress crack corrosion.

● MS 58 brass with pore-free platingis used for metal components not in contact with water

● The threads are designed to be resistant to torsion and are suitable for the building site.

● Threads conform to DIN 2999

Remarkable properties

● Elastic despite high rigidity

● Excellent chemical resistancefor defined operating conditions

● The raw materials conform to foodstuffregulations (LMG 1975)ÖN B5014

Important:Any remains of PUR foam on pipes whichhave been cut to size must be completelyremoved mechanically before the fusionwelding can be done!

KEtrix®-CX:The modern solutionfor the problem ofexpansion

Common applications:Pipes in the cellar, garages, risers,industrial pipes in buildings

Function:The KEtrix® raw material has a very lowelasticity module compared to steel.This means that the expansion can berestrained to ”zero” using very little forceand at the same time provide excellentinsulation against heat loss or heat gain.

Fittings:Pre-insulated elbows and tees areavailable on request.

In general only non-insulated fittings areused which are then insulated at a laterpoint by specialist companies.

Advantages● Practically no linear expansion

of exposed KEtrix®CX pipes

● Pipes can be clamped without theneed to remove insulation

● High mechanical strength protects against damage

● Excellent heat insulation providedby evenly distributed PUR foam

KEtrix®polyfusionwelding withthe hand weldingmachine

1. The pipes and fittings are joined bypolyfusion welding at 260°C. The weldingmachines and tools are self-regulating.Just connect to the electricity supply (230V)and wait:The red light indicates that the machine isconnected to the electricity supply.When the green light goes out the weldingtemperature has been reached.Work can begin.Measure the length of the pipe required(including the length of pipe required to weldinto the sockets).

1.1 Before welding the ALU compositepipe sufficient aluminium must be removedby the peeler to allow the pipe to be weldedto the full depth of the socket.

Important: There should be no aluminiumin the welding area. Make a visual checkbefore welding!The pipe can then be welded to the fittings inthe same way as the standard KEtrix®pipe.

The welding procedure

2. Ensure that the surface of the pipes areclean and free of grease.

2.1 Measure the depth of the socket andmark the insertion depth accordingly.

2.2 The heating time (see table) begins whenthe full insertion depth of the pipe and thewhole of the socket in the fitting have beenpushed on to the welding tools.

2.3 The heating time varies according to thepipe size (see table). Once the heating timehas elapsed push the pipe and fitting togethersmoothly and evenly without delay. The resultis a homogenous and strong joint.

2.4 Three lines on the pipe (90° apart) actas a guide for making a straight joint.

2.5 The position of the fitting can be adjustedfor a few seconds (see table) immediatelyafter the pipe and fitting have been joined. Ashort time later (see table) the joint is capableof withstanding operating conditions.

3. The low weight and high flexibility ofthe material makes it possible to weld wholesections of the piping at the work bench. Takeadvantage of this and save a lot of time.

4. The pipes should be insulated accordingto the relevant national standards.

2.2 2.44. Once the heating time is over the saddlefitting is immediately pushed into the pipewall (do not twist!) and pressed for approx.30 sec. The melting of both the pipe walland the pipe surface ensures a stronghomogenous joint. After approx. 10 minutesthe joint can be subjected to operatingconditions.

3. If the saddle fitting is being connectedto an ALU composite pipe use the peelingtool to remove the aluminium layer.

3.1 A wide range of fittings are availablein different sizes.

2. A hole is drilled in the pipe using a24 mm saddle drill.

Welding KEtrix®saddlefittings1. The surface of the pipes and saddlefittings should be free of grease,clean and dry.

Table weldingmachine

1. Screw the required heating elementsto the welding plate. The length of theheating plate varies according to the sizeof the pipe and the section of pipe to bewelded.

2. One side of the fitting clamps canbe used for small pipe sizes (d20-40).For larger sizes (d50-d90) the clampsshould be turned around.

3. The same principle applies for thepipe clamps.

4. Set the pipe diameter switch to therequired size. This switch regulates thelength of the pipe that will be welded intothe socket.

5. Spacing buttonPress the button to fix the distancebetween the two sliding blocks which willenable the appropriate section of pipeand the complete socket of the fitting tobe heated on the welding elements.

1.3 Release the spacing button.Only now fix the pipe in the clamp.

2. Move the sliding blocks apart andpull down the welding plate.

2.1 Move the sliding blocks together untilthey are stopped by the lock.

2.2 When the heating time has elapsedmove the sliding blocks apart briskly andremove the welding plate.

3. Push the sliding blocks togetherbriskly until the pipe diameter switchcatches.

3.1 Never cool the welded joint abruptly.After a while loosen the clamp and thefinished joint can be removed from themachine.

3.2 Once the cooling time has elapsedthe joint can be subjected to operatingconditions.

1.1 To provide extra support the pipeshould be clamped close to a pipe bracket

1.2 A pole can be placed under the centreof gravity to support the machine ifnecessary.

1.3 The pipe should protrude far enoughout of the pipe clamp to ensure that thepipe can be fully welded into the socket ofthe fitting but also allow enough space forthe welding plate.

The space between the pipe and thefitting when the sliding block hasbeen completely rolled back shouldbe approx. 100 to 150 mm.

2. Put the fitting in the clamp and supportthe fitting with the fixing elbow. The fittingmust have sufficient room to move sidewaysso that the whole of the socket can bewelded.

3. Put the welding plate between the pipeand fitting. Turn the hand wheel to movethe pipe and fitting. Heat the pipe andfitting.

3.1 When the heating time is over removethe welding plate and push the pipe andfitting together briskly to weld the joint.

3.2 When the cooling time is over the jointcan be subjected to operating conditions.

Butt welding machinefor KEtrix®pipes

30mm

IMPORTANT:The pipes cannot be touched and must bewelded immediately.If this is impossible and the welding hasto be done later then the welding surfacehas to be cleaned and any greaseremoved.

1. Loosen the screws and fit the requiredreducers in the clamps.

1.1 The end of the pipes should protrudefrom the clamps by no more than 30 mm.

2. Put the surface cutter between the pipeends. Move the pipes together and removethe oxide layer on the welding surface bycutting away 0.2mm of the surface. Ensurethat the ends of the pipes are verticallyparallel to each other (maximum deviation:0.3 mm). The maximum deviationhorizontally is 0.5 mm.

3. The welding procedure(see table on the left for welding criteria)

3.1 Before welding begins read off themanometer the pressure required to bringthe pipes together. This pressure must beadded to the joining pressure given inthe table.

3.2 Insert the heating element (temp:approx. 210°C). Press the pipe ends on theheating element and apply the pressureas defined in 3.1 until a bead forms aroundthe complete circumference of the pipe.During the heating time the pressuremust be reduced to the heating pressure.Once the heating time is over move thesliding blocks apart rapidly and remove theheating element.

3.3 The change over time (time betweenremoving the heating element and weldingthe pipes) should be as short as possible.

3.4 The welding pressure should bebuilt up as smoothly as possible during thetime given in the table(minimum: 0.15 N/mm2).

3.5 The welding pressure must bemaintained during the cooling time.

Never cool the joint abruptly.If the weld has been done correctly adouble bead should be visible around thewhole circumference of the pipe.

Ensure that the cable iscompletely unrolled to avoidinductive loss of voltage.

6.1 Turn on the main switch. Thelight next to ”Power” will switch on.

6.2 Connect the welding cable tothe socket. The light next to”Sleeve connected” will switch on.

6.3 Press the ”start” button. Thelight next to ”welding in process”will switch on.The welding machine calculates thewelding time automatically.

6.4 When the welding time is overthe machine will switch off and thelight next to ”Welding over” willcome on. Check whether the orangetracers have emerged from the socketsto show that the weld has beensuccessfully completed.

6.5 Press the ”Reset” button beforeeach new weld.

6.6 If there is a defect ”Incorrectwelding” and ”Welding over” willlight up. Establish the cause and ifnecessary wait for one hour for the E-socket to cool down, press the ”reset”button and start again with theprocedure in point 6.

5.1 In order to guarantee the centralposition of the weld, mark the weldingdepth of the socket on the pipe. For pipeswhich are being installed horizontally tryto ensure that the tracers point upwards.

3. Alu peelers are available for removingthe aluminium layer from the Alu pipes(please note that more aluminium has tobe removed from an electrofusion socketthan for a standard socket).

4. Remove any grease from the end ofthe pipes and the electrofusion socketsin the areas where the weld is going tobe made. This should be done with thecleaning tissue (soaked in isopropylalcohol) which is supplied with theE-socket.No oil-based solvents (e.g. paint thinner)should be used to clean the socket.

1. Cut the KEtrix® pipe atright angles.

2. Scrape the surface of the KEtrix®pipe with a suitable tool, e.g. a blade(DO NOT use sandpaper).

A thin layer must be removed from thepipe. At the same time the diameter shouldnot be reduced below its nominal value. 5. By cutting out the buffer in the middle

of the socket the e-socket can be pushedcompletely over the pipe.

7. Ensure that the electrofusionsocket is axial to the pipe and is notsubjected to stress or strain duringwelding.

8. Ensure that no moisture is presenteither inside or outside the weldingzone during welding.

9. Ensure that the weld is notsubjected to stress, impact, moistureor any other strain during the coolingperiod (allow at least 10 minutes forcooling).

10. Wait for at least one hour beforepressure testing or subjecting tooperating conditions

bursting effectbelow the anti-freezing point(solid)

Pressure loss inKEtrix® drinkingwater pipesThe total pressure loss (∆p) of the KEtrix®pipe system is calculated by multiplyingthe friction loss (R) by the length of thepiping (l) plus the sum (∑) of the frictionloss for the individual fittings (Z).

Total pressure loss ∆p∆p = (l . R + ∑ Z) in Pa

The choice of pipe size for the watersupply is dependent on the followingfactors:● The available water pressure● Geodetic difference in height● Pressure losses through system components● Minimum flow pressure through faucets● Pressure losses in the pipes● The individual pressure losses of the fittings● Type, number and simultaneous use of

the draw-off points● Flow velocity

The viscosity of glycol water fluids is muchhigher than water. The pressure lossesmust be adjusted by the factors in thefollowing charts and as a result therequired pipe sizes are larger(see pages 32 and 33).

Guidelines forpipe sizing(DIN 1988/3)

1. Determine the design flow rateand minimum flow pressure forall the draw-off fittings.

The design flow rate VR is derived fromthe draw-off fitting flow rate. The tablebelow gives guideline values for thedesign flow rate of common types offittings and appliances.The design flow rate VR may bedetermined as a mean value using thefollowing equation:

V̇R = V̇min + V̇max2

2. Determine total flow rates andassign to pipe runs

The design flow rates for all draw-offpoints shall be added, starting at thedraw-off point furthest from the watermain and ending at the water main,and the total flow rates so obtainedassigned to the pipe runs considered,each run extending from the fittingwhere the total flow rate or pipediameter changes until the next fitting.

At the junction of the cold waterpipe feeding the water heater withthe pipe branches off, the totalflow rate comprises that of thecold and hot water side.

3. Use of total flow rate / peakflow rate

The design flow rate of all draw-offpoints shall be included in the designof water supply system, adding the flowrate of the draw-off points for whichcontinuous use is to be assumed to thepeak flow rate of the draw-off points(continuous use being defined as uselasting more than 15 minutes)Assumptions regarding simultaneousdemand are to be based on the typeof building or its occupation (e.g.residential building or communalfacility).Normally it may be assumed that notall draw-off fittings are fully open atthe same time.The conversion curves for the differentapplications are shown on pages 30and 31.

4. Determination of diameter

Determine the pipe size, pressure lossand flow velocity (see pressure losscharts on pages 30 and 31)

5. Evaluation of head loss in termsof available pressure

The head loss shall be almost equal tobut not greater than the available totalhead loss

For hot water systems use theKELEN® pipe system in eitherPN16 or PN20 pressure rating,made of grey PP-R material.

Note:● For any outlets or apparatus not included

above or similar to the above with a different flow rate please follow the manufacturers instructions regarding the sizing of the pipes.

● For the purpose of pipe sizing it is assumedthat there will be no reduction in theinternal diameter caused by incrustation since the surface structure of the pipe isamorphous and the surface roughness of the pipe is minimal (0.007).

Hotels, department stores, hospitals

If the system is equipped with draw-off fittings with a design flow rate of V̇R≥ 0,5 l/s then where the total flowrate is ≤ 1,0 l/s the peak flow rate shallbe deemed to be equal to the total flowrate. If the total flow rate is >1,0 l/sand ≤ 20 l/s curve K (equation: V̇S=(∑V̇R)0,366 in l/s) is used for calculatingthe peak flow rate.

Other special buildings,commercial and industrialpremises

Particular considerations must be givento the extent to which simultaneousdemand is to be assumed for watersupply systems on commercial and tradepremises. The total flow rate isdetermined in consultation with theoperator of the system.

Excerpt fromDIN 1988/3

Residential buildings

An additional wash basin, sitz bath, WC,urinal, and shower unit (in addition to thebath tub) need not be allowed for indetermining the total flow rate if it maybe assumed that the level of simultaneoususe will not be increased by the use oftheir appliances.

Schools

The peak flow rate is deemed to beequal to the design flow rate where∑VR ≤ 1,5 l/s

Special case

If the system is equipped with draw-offfittings with a design flow rate of V̇R≥ 0,5 l/s then, where the total flowrate is between 0,5 l/s and1,0 l/s the peak flow rate shall bedeemed to be equal to the total flow rate.If the total flow rate is ≥ 1,0 l/s curveB shall be used.

The compressed airnetwork PN16If the compressed air is to be suppliedcentrally a pipe network will be requiredto supply the air to the individual units.In order to operate efficiently the networkhas to fulfil the following requirements:

● Sufficient volume flow– for each unit

● Required working pressure– for each unit

● Quality of the compressed air– to ensure that system operates smoothly

● Pressure loss– as low as possible

● Operational liability– maintenance and repairs shouldnot shut down the whole network

● Safety requirements– to prevent accidents

The quality ofcompressed airThe compressed air can be divided intodifferent quality categories which can beclassified according to the application.

The pressure dew pointAs a result of the compression of the air thewater content in the compressed air risesgreatly. Drying the air reduces the formationof condensation inside the system to theminimum possible. The pressure dew pointis the temperature at which the water withinthe compressed air starts to condense and iscategorised in different classifications.

The solidsSolid impurities found in the air are alsopresent in compressed air and must bereduced by filtration. The particle sizes andconcentrations are specified in differentclassifications.

The oil concentrationCompressors require at least some lubricatingoil for the working process. Depending onthe application various procedures must beundertaken to remove this oil from thecompressed air. The oil concentration is alsodivided into different categories

Main pipeline

The pipe network

Circulation pipeline

Conclusion:The flow velocity ofcompressed air in pipelinesis usually 2 – 3 m/sec andshould not exceed 20 m/secin order to avoid noise andturbulent flow.

The main pipelineThe sum of the required supply to all ofthe distributor pipes

The distributor pipelinesThe distributor pipelines transport thecompressed air from the main pipeline tothe connecting pipeline. If possible thispipeline should be a circulation pipeline.The advantage of a circulation pipelinecompared to a direct pipeline:A circulation pipeline is a closed circuit.It is possible to shut off sections of thepipe network without disrupting the supplyof compressed air in other parts of thenetwork. This will increase the economicefficiency and operational security of thesystem. In a circulation pipeline thecompressed air has less distance to travelthan in a direct pipeline system. Thiswill mean a lower pressure drop; ∆p.

In a circulation pipeline the size ofthe pipe is calculated with half theflow volume of a direct pipeline.Connecting pipelineThe connecting pipelines branch off fromthe distributing pipelines.

Pipe sizing forcompressed airsystems PN16For economic reasons it is important tocalculate the pipe sizes accurately.

The main factors affecting the size of thepipe are as follows:

● V̇ = Total volume flow [l/s]● l = Fluidic pipe length [m])

The equivalent pipe lengths of the elbows, fittings or other units mustbe added.

● p = operating pressure [bar]is dependant on the cut-in pressureof the compressor

● ∆p = pressure drop [bar]The max. pressure drop in the individual sections of piping shouldnot exceed the following:Main pipeline: ≤ 0,04 barDistributing pipeline: ≤ 0,04 barCirculation pipeline: ≤ 0,04 barConnecting pipeline: ≤ 0,03 barThe total pressure loss in the completenetwork should be ≤ 0,1 bar.

Calculation of the inside diameterof the pipe

The required inside diameter (di) can becalculated using the following formula:

It is easier and quicker to calculate thepipe size by using the nomographbelow. The determining factors are thesame for both methods of calculatingthe pipe size.

Requirement for compressed airfor toolsThe volume flow must account for therequirements of all the tools andappliances.Machine and tool manufacturers canprovide information about the airrequirements for their appliances.Any calculation factors for simultaneoususe are to be specified by the consultantor operator since there are no empiricalvalues that can be considered a basis forcalculation.

Equivalent pipe lengthsAn important factor when calculating thesizes of the pipes is the length of the pipes.Elbows, valves and other fittings greatlyincrease the flow resistance in the pipesand must be accounted for.To make the calculation easier the flowresistance in the various fittings isconverted into the equivalent pipe lengths.The table below shows the equivalent pipelength for the fittings in different sizes:

Practical solutions forcompensatingexpansionThe following methods can be used tocontrol the linear expansion and the forceof expansion.

● Piping that is embedded in the floor or the wall is prevented from expansion by frictional force. No extra measures are required.

● Every change in temperature willexert a force.

An expansion force will occur when the temperature rises.A force of contraction will occur whenthe temperature falls.

● Suppliers of pipe clamps and bracketsknow the properties of the materialsand offer a range of solutions.

● Pipe channels may be used to increasethe stability of the pipe.The expansion is reduced to the samevalue as steel pipes.

● Compensation must be made for expansion of exposed piping.

● Think of the option of usingKEtrix®-CX pipes. The expansion of exposed piping is effectively restrictedand they provide excellent insulationagainst heat gain and heat loss.

● The expansion can be minimised by installing the Ketrix ALU pipes(d20 – 32). This pipe reduces the expansion by approx. 75%.

The force of expansion can becalculated for every installation.However, in general the force isjust a fraction of the force whichoccurs with metal materials.

Force of heatexpansion

The force of linear expansion is differentfor each material. The specific force ofheat expansion is calculated according tothe following formula:

E = E-module of KEtrix® [N/mm2]A = Cross sectional surface

area of pipe [mm2]α = Coefficient of expansion [mm/mC°]∆ t = Difference between temperature

at time of installation and operating > temperature [°C]F t = force of expansion [N]

The force of heat expansion(or cooling contraction) is dependanton the dimension of the pipe andthe change of temperature but noton the length of piping.An important factor is the rigidity of thematerial (E-module).

The E-module of Cryolen (like any otherplastic) is dependent on the temperature(see graph below)

> Temperature < E-module < Temperature > E-moduleThe force of heat expansion is thereforean important criteria when planning aninstallation.

E-module of cryolen

Ft = E · A · α · ∆ t1000

Example:A d50 pipe runs over a length of 15 m.∆t = 18 °C.Question: How long does the expansionarm have to be to compensate for theexpansion?

Calculation of the expansion arm:

MS= 22 · d · ∆ l22 = coefficient for KEtrix®∆l = change in length [mm]d = outside diameter of pipe [mm]MS = Minimum length of the

expansion arm [mm]Length of pipe which branchesoff at 90° from the main pipe to the next fixed point.

Expansion arm forexposed piping

Compensation must be made for theexpansion of KEtrix® pipes under heatconditions.

Even if the rise in temperature is only fora short time sufficient compensation mustbe made for this temperature difference.

Compensation is always made between afixed point and a change in direction ofthe piping (expansion arm).

Expansion behaviourof KETRIX pipes

Linear heatexpansion

Under heat conditions all materialsincrease in volume and/or lengthaccording to the following formula:

This means that when heatedKEtrix® will expand more thanmetal materials if the expansionis unhindered.

Steel α = 0,012 mm/m°CCopper α = 0,016 mm/m°CKELOX® α = 0,025 mm/m°CKEtrix® ALU α = 0,030 mm/m°CKEtrix® α = 0,140 mm/m°CPEX α = 0,175 mm/m°C

Coefficientsof expansion

Calculation of the linear expansion:

∆ l = l ·∆t · l = length [m]∆t = difference between temperature

at time of installation andoperating temperature [°C]

α = coefficient of expansion[mm/m°C]

∆l = expansion [mm]

The linear expansion is determinedby the length of the pipe, theincrease in temperature and thecoefficient of expansion.It is not determined by the diameterof the pipe.

∆ l = 15 · 18 · 0,14∆ l = 37,8 mm expansion

MS = 22 · 50 · 37,8MS = 956 mm expansion arm

Installing KEtrixInstalling the pipes in the shaft

In practice the main risers can expand and contractlaterally in the shaft between two floors if a fixedpoint is located next to the pipe that branchesoff from the main pipe. The distance between two fixedpoints should not exceed 3 m. Other methods can beused to accommodate expansion such as an expansionarm in the pipe branching off from the riser.

Exposed piping

Preventing expansion by mechanical restraintd20 – d50

In order to achieve this stability all of the pipes mustbe supported by pipe channels and all of the bracketsmust be fastened tightly to the pipe to make themfixed points. In addition the channels are fixed to thepipe (e.g. using cable ties)*.This method reduces thelinear expansion to the sameamount as steel.

Up to size d32 KEtrix Alupipes are usually preferred.

Expansion loopsd63 – d160

All changes in the direction of the pipe can be used toaccommodate the linear expansion. In some cases anexpansion loop will be necessary.The fixed points are arrangedso that the piping is dividedinto sections and theexpansion force can be guidedin the desired direction.See page 38 for thecalculation of the lengthof the expansion arm.

Guidelines fordistance betweenpipe support points

Condensation

In order to prevent corrosion ordisruptions in the operation of the systemattention must be paid to anycondensation that is formed:

a) by effective air drying(zeolite, silica gel ….)

b) by a water trap before the connections to the apparatus

c) by installing a ”swan´s neck”joint to the connecting pipeline.

● The distances between the support points given below (in cm) prevent KELEN pipes from sagging when theyare filled with water and there are NOpipe channels.

● Pipes containing compressed air are subject to much greater changes in length than pipes filled with water when the temperature fluctuates as the medium has no cooling effect. Longer runs can be split up into expansion zones and the fixed pointslocated accordingly.

Suppliers of pipe clamps and bracketsknow the properties of the materialsand offer a range of solutions.

For sizes d20 – 32 we recommend the use of pipe channels. If pipe channels are usedthen we recommend a maximum distance of 180 cm between the support points

KE KELIT recommends pressure testing toDIN 1988/2 for plastic pipes as statedbelow.

As a result of the material properties ofplastic pipes the pipe will expand duringthe pressure testing. The pressure testingis split into a preliminary test and a maintest. The preliminary test is sufficient forsmall sections of the piping such asconnecting pipes and distributing pipesin the wet rooms.

a) Preparation

1. After the pipes have been installed and before they are concealed the piping is filled with water and any airremoved.

2. If possible the pump should be placedat the lowest point in the system

3. The manometer should be capableof reading changes in pressure of0,1 bar and should be placed at the lowest point of the section of piping being tested.

Pressure testingfor drinking watersystems

b) Preliminary testing

The test pressure is equal to the maximumoperating pressure of the system plus 5bar (minimum: 15 bar). The test pressuremust be built up over a period of 30minutes. Within the 30 minutes thepressure should be re-adjusted 2 times(each time 10 minutes apart). After afurther period of 30 minutes underpressure testing there should be no leaksand the drop in pressure should notexceed 0,6 bar.

c) Main testing

The main testing should be carried outimmediately after the preliminary testing.The duration of the test is 2 hours. Thedrop in pressure between the end of thepreliminary testing and the end of the 2hour main test must not exceed 0,2 bar.

After the pressure testing has beencompleted we recommend issuing aconfirmed report.

Please note:● Fluctuations in the temperature

may alter the test pressure

● Every pressure test is an assessment of the current stateof the system and is no guarantee against any mistakesmade during installation.

Testing for leakages by gas pipe device (water head manometer)

The test pressure is 110mbar (1,1 m head of water)The testing time is a minimum of 30 minutes for up to 100 litres volume. For everyextra 100 litres of volume add 10 minutes to the testing time (see page 8 for volume).

Wait for approx. 15 minutes to allow for temperature equalization and for the air tosettle. The testing time can then begin.

Test pressure ...... mbarVolume ...... litreAmbient temperature ...... °CTesting time ...... minutes

During the testing time there was NO drop in pressure.

Strength testing at higher pressureThe strength test immediately follows the leakage test. The test pressure should be1,1 times the maximum operating temperature. Two times during the following30 minutes the pressure should be re-set at the testing pressure to compensate for anydrop in pressure. After that the testing pressure should be held constant for 30 minutes.

Test pressure: ...... bar

During the testing time the drop in pressure did not exceed ≥ 0,1 bar.

7.Avoid using heat to bend the pipes(it is possible to bendthe cold pipe to a

radius of 12 x d). If the pipe has to beheated then only use hot air (max.140°C). Never heat the pipe with a nakedflame! On request KE KELIT can make anoffer for manufacturing butt weldedelbows up to 30° in various lengths forsize d50 mm and above.

8.Try to make the jointsfor standard sectionsof piping at the workbench before they are

installed. This saves time and increasesthe safety of the system.

6.The expansion ofKEtrix® pipes isclearly defined andmust be accounted for

in the design and installation of the system.Please refer to pages 38-40 regardingthe methods of accommodating theexpansion of exposed piping.

Pipes containing compressed air are subjectto much greater changes in length thanpipes filled with water when thetemperature fluctuates as the mediumhas no cooling effect. Longer runs can besplit up into expansion zones and thefixed points located accordingly.

Suppliers of pipe clamps and bracketsknow the properties of the materials andoffer a range of solutions.

5.Do NOT screw anythreaded pipes or anycast iron fittings intothe female threads of

the metal moulded fittings.Only join to faucets and components withstraight threads, The threaded joints canbe sealed by the usual methods (hemp,paste, tape)Do not over-screw the threads.

4.Any corrections to thealignment of pipe andfitting up to amaximum of 5° must

be made during the welding procedure.Any later adjustments would damage thejoint (see pages 17, 19 and 21 for thepermissible time for adjustments).

2.Protect the pipes,fittings and opponentsfrom lengthy exposureto direct UV radiationfrom the sun.

The usual time required for storage andinstallation will have no effect on thematerial as it is stabilised against UV raysbut the material is not resistant to long-term UV exposure

1.The KEtrix® pipesystem is made ofplastic and needs to betreated carefully to

prevent shocks and impact on the pipeduring transportation, storage andinstallation.

3.Follow the installationguidelines for thedifferent methods ofjoining the pipes(see pages 16 – 25).

The welding times are based on anambient temperature of 20°C.If the ambient temperature falls below0°C the heating times may alter slightly.

10.The KEtrix® pipesystem is designed forthe applicationsdescribed in this

°C

handbook. Extra stress on the system causedby higher temperatures or pressure couldreduce the service life and security of thesystem.
